在arx中自定义实体遇到的问题

我在arx中自定义了一个类，但在加到数据库的时候发生错误，想问一下是否需要什么注册的操作？是否只能在dbx中写啊？谢谢

class EObject:public AcDbEntity
{
protected:
char *m_name;
Adesk::Int32 m_ID;
char *m_location;
AcGePoint3d m_center;
public:
EObject();
virtual ~EObject(){}
virtual Adesk::Boolean worldDraw (AcGiWorldDraw *mode);
virtual Acad::ErrorStatus getGeomExtents(AcDbExtents & extents);
virtual Acad::ErrorStatus transformBy(const AcGeFastTransform& xform);
virtual Acad::ErrorStatus getTransformedCopy(const AcGeMatrix3d &xform, AcDbEntity *&pEnt);

virtual Acad::ErrorStatus moveGripPointsAt(const AcDbIntArray &indices,const AcGeVector3d &offset);
